SBEGIFIGATION forming part of Letters Patent No. 731,587, dated June 23,1903. Application filed December 11, 1902. Serial No. 134,824 (Nomodel.)

To all rah/omit may concern,- Be it known that I, ROBERT K. MARPLE, re-

' sidingatPhiladelphia, in the county or Philadelphiaand State ofPennsylvania, have invented certain new and useful Improvements inStaple-Machines, of which the following is a specification.

This invention relates to mechanism adapted for cutting blanks, formingthem into staples, and driving and riveting'such staples. It has as itsprimary object to'produce a simplified machine for effecting theseoperations and to render the parts readily changeable in order to adaptthe mechanism to the character of the work The nature and characteristicfeatures of the improvements will more fully appear by vil 3, the latterbeing preferably movable to vary its height with reference to the stem.A cam wheel or disk 4t is journaled on the arbor 4', supported by theframe, and has the cam-grooves 5 and 6 formed in the face thereof. Thegroove 5 operates the plunger 7 bymeans ofits engagement with the roller8 on the plunger. This plunger is adapted to reciprocate in the stem 2and has fixed thereon astop9, which moves in the recess 9', formed inthestem, and limits the upward movement of the plunger with relation to thestem aswell as its downward movement with relatiou'to.thediethereon. Thedie 10 is sleeved on the lower end of the plunger 7 and is movablyengaged therewith by a screw 10, which passes through the die andprojects into a blind channel 7, formed in the plunf. gerl A die 11,coacting with the die 10, is;

sleeved on the pin 12 and lies within the socket 13 of the arm 14, thedie 11 being cushioned upon the spring 15, located in the socket. Aknifel6 is attached to the socket and is adapted to coact with the edgeof the die 10 in shearing blanks from a metallic ribbon 23 fed betweenthe dies. The cutting mechanism may he modified, however, by omittingthe knife 16 and attaching a knife 17 to the lower die, so as to projectabove the same and coact with the edge of the upper die in cutting theblanks, the spring 15 being provided with sufficient resistance toeffect the cutting operations. A rod 18, fixed to the arm 14, is adaptedto reciprocate in a bearing 19 on the stem, the rod having therein aworm or cam-groove 20, which receives a pin or boss 21, fixed in thebearing. An arm or hearing 22, to which the rod 18 is revolublyconnected and longitudinally fixed, carries a roller 23, which engagesthe cam-groove 6, the arm being engaged by the stem 2 to prevent theroller leaving the groove.

It will be understood that when the revolving cams 5 and 6 elevate theparts '7 and 18 a metallic ribbon 23, fed by any suitable mechanismbetween the dies 10 and 11, will bepressed by the die 11 against the die10 and out by the knife 16or 17. The blank thus shorn and held betweenthe dies is by the further revolution of the cam-disk 4 and theconsequent further upward movement of the rod 18 forced into the hollowdie 10 against the end of the plunger 7 by the forming-pin 12, thethrust of the stem 2 and the die 1 0,supported thereby, against the die11 compressing the spring 15 and permitting the forming-pin to enter theupper die and form the rivet 21. The further revolution of the cam-diskmoves the rod 18 downward,and by the engagement of the worm 20 with thepin 21 the arm 14: swings the mechanism carried thereby out of the pathof reciprocation of the plunger mechanism comprising the plunger 7 andthe die 10, upon which this plunger mechanism is carried down until thedie 10 strikes the work supported upon the anvil 3 and the plunger 7drives the staple 24.

As the parts are of simple construction and readily changed, themechanism may be varied readily as required for different kinds of work.By changing the cam-disk and providing cam-grooves of various forms thestrokes of the reciprocating parts may be varied at will, the anvilbeing adjustable to accommodate its height to the stroke. There is thusprovided simple and flexible mech- IOO anisln permitting operation inangles and corners of boxes or receptacles of various forms and depths.

Having described my invention, I claim 1. In a machine of the classdescribed, the combination with a support of reciprocating mechanismcomprising a plunger and a die movably sleeved thereon, a secondrecipro' eating mechanism comprising a pin and a die movably sleevedthereon, and means for operating said .mechanisms, substantially asspecified.

2. In a machine of the class described, the combination with a supportof a reciprocating plunger, mechanism for operating said plunger, a diesleeved on the end of said plunger and having a limited-movement inrelation thereto, a reciprocating pin adapted to enter said die, a diemovably sleeved on said pin, and mechanism for reciprocating said seconddie on said pin, substantially as specified.

3. In a machine of the class described, the combination with a supportof reciprocating mechanism comprising a plunger and a die movablysleeved thereon, a second reciprocating mechanism comprising a knife, apin and a die mova'bly sleeved on said pin, and means for operating saidmechanisms, substantially as specified.

4. In a machine of the class described, the combination with asupport ofa reciprocating mechanism comprising a plunger and a die, means foroperating said reciprocating mechanism,a second reciprocating mechanismcomprising a knife, a pin'and a die, and means for swinging said secondreciprocating mechanism out of the path of said first reciprocatingmechanism, substantially as specified.

5. In a machine of the class described, a cam, a reciprocating plungeroperated by said cam, a die sleeved on said plunger and having a limitedmovement thereon, in combination with a forming-pin, shearing mechanism,and means for supporting'said parts, substantially as specified.

6. In a machine of the class described, a cam, a forming-pin connectedtherewith and reciprocated thereby, in combination with a die adapted toreceive said pin, a plunger movable in relation to said die, and a camfor operating said plunger, said cams being rigidly connected,substantially as specified.

7. In a machine of the class described, a cam, a forming-pin connectedtherewith and reciprocated thereby, a die sleeved on said pin andadapted to reciprocate with relation thereto, in combination with areciprocating plunger, a die sleeved on said plunger and adapted toreciprocate with relation thereto,

and means for supporting said parts, substantially as specified.

8. In a machine of the class described, a cam, a forming-pin connectedwith and reciprocated by said cam, a die sleeved on said pin and adaptedto move with relation thereto, a reciprocating plunger, a cam connectedwith said plunger to reciprocate the same, a reciprocating die connectedwith said plunger and having a limited movement with relation thereto,and means for supporting said parts, substantially as specified.
